Here are a few of my favorites:
Brokenwood "Graveyard Vineyard" shiraz (Hunter Valley, Australia)
Brokenwood is an iconic Australian producer that has helped put Hunter Valley semillon on the map. They also make great shiraz: This Halloween-perfect wine is their shiraz from a very special single vineyard called The Graveyard Vineyard. This land was originally designated to be a graveyard, and the old map hangs in the winery today.
Anima Negra "Son Negra" (Mallorca, Spain)
Anima Negra is a winery on the island of Mallorca, one of the Balearic Islands off the coast of Spain. Their "Son Negra" cuvee is made only in the best years from three of their best vineyards. The grape varieties are 95% callet, 5% manto negre and fogoneu. The yields are very, very low (less than half a kilo per vine) which leads to dense and flavorful berries. Fermented in barrels, 17 months barrel aging.
The winemakers have a special friendship with artist Miquel Barceló, who designs the Son Negra labels.
Poe "Angel Camp Vineyard" pinot noir (Anderson Valley, California)
This delicious pinot noir from Anderson Valley has a great label that invokes Edgar Allan Poe's tales of woe-- in this case, The Raven. Poe wines, founded by Samantha Sheehan, produce a single vineyard chardonnay and a single vineyard pinot noir. This pinot noir is made to express terroir-- it's produced from low-yield vines and fermented on its own yeasts.
Cayuse Vineyards "Bionic Frog" syrah (Walla Walla Valley, Washington)
This is a small production syrah and it's pretty hard to find. But if you can get your hands on some, it will be worth it. The inky brew is made in Walla Walla Valley, Washington at Cayuse Vineyards. All the vineyards are farmed using biodynamics, and the wine is dense, meaty, and complex. Plus, the label has so much personality it's almost as if the bottle wears its own costume...
Some Young Punks "Monsters Attack" riesling (Clare Valley, Australia)
This label is reminiscent of an old pulp fiction novel, and is a great match with the ghouls and monsters that might ring your doorbell on Halloween night. It's made by the renegade winemaking group, Some Young Punks, who have become known for their over-the-top label designs and approachable wines. This riesling is from a small, family owned, organic vineyard in the Clare Valley. It's slightly off dry (might remind you of your average spätlese), and is the perfect Halloween candy for adults of legal drinking age.
